• PubMed Abstract: 
  

  Solved crystal structures of P450 BM3 variants in complex with styrene provide on the molecular level a first explanation of how a positively charged surface residue inverts the enantiopreference of styrene epoxidation. The obtained insights into productive and non-productive styrene binding modes deepened our understanding of enantioselective epoxidation with P450 BM3.
